Supercritical fluid technology for greener processes

S
upercritical fluid technology is one of the most promising green chemistry-based future technologies which can develop new, better
and clean processes and products. In this presentation, recent R&D activities of supercritical fluid technology are briefly discussed
with emphasis on the commercialization efforts. Discussion includes the large-scale (3,000 MT of sesame oil/yr) supercritical fluid
extraction (SFE) processes of sesame oil inKorea inwhich sesame oil contains rich antioxidants like sesamin, sesaminol, and sesamolin.
Supercritical CO
2
extraction of residual solvent fromActive Pharmaceutical Ingredient (Cefpodoxime Proxetil) preventing unwanted
agglomeration of particles will be also discussed. A correlation between the agglomeration phenomenon and dimensionless entropy
of fusion (ΔSm/R) was shown on the basis of the hypothesis that CO
2
-induced melting point depression is one of the major factors
resulting in agglomerates. Other examples of application of supercritical water to wastewater treatment, nano particle synthesis, and
recycling of cross-linked polyethylene will be discussed.
